Application filed August 13,1901. Serial No. 71,896,

Be it known that I, HARRY L. DUNCAN, a resident of New York, county ofKings, and State of New York, have invented a new and useful Improvementin Daling-Presses, of which the following is a speciiication, taken inconnection with the accompanying drawings, in which the same referencecharacter rei'ers to similar parts in the several iigures.

This invention relates to baling-presses for producing continuously acylindrical bale of fibrous material, preferably composed of suhelicallayers; andit relates more specifically to baling-presses in which thecontinuous bale is separated in the balingchamber into separate bales,and these bales are held against rexpansion and in proper compressedcondition as they are continuously fed from the baling-chamber.

1n the accompanying drawings, Figure 1 shows in axial section one formof such a baling-press. Figs. 2, 3, and i are partial transversesectional views taken on the lines 2 2, 3 3, and 4 4'of Fig. 1. lig. 5is a perspective view of a retainer. Fig. is a partial transversesectional view taken substantially through the ejectors. Fig. 7 shows intransverse section a modified form of bale-governing device as appliedto the baling-chamber, talien on line 7 7 of Fig. S. big. 8 is asubstantially axial section of the same, taken on line 8 8 of big. 7.Fig. 9 is an enlarged detail showing the bat forming and feedingmechanism, taken on the line 9 9 of l`rig. 10. Fig. 10 is another viewof the same in elevation, taken from the right of Fig. 9. Fig. 11 is anaxial section through a modified form of baling-press. Fig. 12 is apartial transverse section taken on line 12 12 of Fig. 11. Fig. 13 is adetail in substantial axial section, showing the construction of amodified form of ejector.

This press is composed of a relatively rotating baling-chamber B andslotted capplate A, the baling-chamber being provided with suitableretainer-slots B2, extending longitudinally of the same, through whichbalesevering retainers D are from time to time introduced into thecontinuous forming-bale within the chamber and serve to divide it intoseparate bales. The baling-chamber is also provided with suitableejecting or baleregulating means, by which the movement of thecontinuous bale through the balingchamber is regulated. T he cap-plateis provided with suitable condensing-cones I and feeding-cones G,serving to form bats of material and feed them into the slottedcap-plate. T he baling-chamber B is substantially cylindrical, as shownin Fig. 1, and is formed with a slightly-tapering upper portion. Thisbalingchamber is preferably stationary in this form of press, althoughit may be rotated, if desired. The cap-plate A is revolubly mounted withrespect to the baling-chamber, the Bange B on the baling-chamber beingclamped againstthe cap -plate by the collar A2, secured to the cap-plateby bolts, as shown. The cap-plate is revolved by the gear A, which isdriven by any suitable mechanism at any desired rate of speed. ln thecap plate are mounted the two feedingcones G, rigidly secured to thestub-shafts GL at their outer ends and rotated by means of the beveledpinions G3, secured to them. These pinions mesh with the driving-gearB8, formed at the upper end of the baling-chamber, so that relativemovement between the baling-chamber and the cap-plate serves to rotatethese feeding-cones at substantially the same surface speed as theforming-bale with which they come in contact. rhe shafts G4 aresupported in heavy bearings in the cap-plate A8, and the inner end ofthe feeding-cones are preferably formed with liournals G5, which havesuitable bearing in the feederbearing A9 at the center of the cap-plate,although this center bearing may be omitted, if desired. it isunderstood, of course, that the feeder-journals G5 are slightlyout ofline at the center of the cap-plate, so that the two feed-openings whichextend 'substantially along the diameter of the cap-plate substantiallycoincide at the center of the same. The supplemental bearing-yoke A4,rigidly secured to the cap-plate, as is indicated in Fig. 9, serves tosupport the feeder-cone, since it comes in contact with the bearingportion G2, which may be located near the center of the comb, asindicated in Fig. 1, so as to support this comb at the center and resistthe upward pressure upon it. feeder-cones G are formed with suitablecorrugations G', by which they more readily engage the material and feedit into the feedslot A3 ofthe cap-plate.

lt will be noted by reference to Fig. 9 that the inner surface of thecap-plate is formed with a relieved portion A6 on its under surfaceadjacent each feed-cone, so that the material compressed against theupper end of the forming-bale under the cap-plate is re- As isindicated, the

IOS

leased from close contact at this point, and the material is therebydisengaged from the feeding-cone. The edge of the cap-plate A5 at thispoint closely engages the feeding-cone and serves to assist in freeingthe material from the feed-cone.

Instead of forming the cap-plate with a substantially ilat innersurface, as is indicated, this cap-plate may be formed with a conicalinner surface, as is indicated in my Patent No. 671,918, April 9, 1901,the condensercones and the feeding-cones being so placed that theirapices still substantially coincide with the axis of the press. The twocondensing-cones I are mounted by means of suitable journals I', whichhave bearing in the central portion A9 of the cap-plate, and by thebearing-collar H, which engages a suitable bearing I2 in the bearingmember H. This condenser-cone is formed of perforated or foraminousmaterial, as is usual in this art, and is driven by the beveled gear I3,secured to the collar H, which is driven by the idler G, rigidly securedto the stub-shaft G7, mounted in suitable bearing in the bearing memberH. This idler is driven in turn by the feeder-gear G3, so that, asindicated in Fig. 9, the condenser-cone and the adjacent feeding-conerevolve in the same direction and at substantially the same surfacespeed, although in practice I refer to operate the feeding-cone at aslight y-greater speed than the corresponding portion of the condensercone. Within the condenser is located the shield I5, supported on acentral rod I4, bolted to the outer bearing member H, which is rigidlysecured to the bearing member Hin any desired way. Each condenser coneis provided with a series of slides I7, asis indicated in Fig. 9, theseslides being mounted to move slightly about the axis of thecondenser-cone and being adjustable in any desired position by the boltand nut I8, secured to the slide and operating in a slot in the casingH2. The cover-plate I9 lits over this slot and is engaged by the nut, asis indicated. To the upper end of each one of these slides ispermanently secured the single flexible curtain or cover strip I, whichis fastened at its upper end to the side of the casing H2. In this wayas the slides I7 at various parts of the condenser-cone are moved aboutthe axis of the cone the cover-strip serves to shield a greater or lessportion of the condensercone at that point from the lint or blast ofmaterial which is continuously fed to the condenser-cone. In this waythe active angle of the condenser-cone may be adjusted at various pointsalong the cone to form a bat of any desired cross -section It will ofcourse be understood that any desired number of slides may be employed,so that any desired nicety of adjustment may be obtained in this way.The action of this adjustable bat-former is similar to that set forth inmy Patent No. 672,394, April 1c, 1901.

-ner or feeding chamber is connected with the cylindrical feed-pipe,(not shown,) which serves to supply a blast of material-such as cotton,wool, or other fibrous material-to each of the condenser-cones, whilethe annular exhaust-space H3, which communicates with the interior ofthe condensercones through the bearing-collars H9 of the same, serves tocreate a suction within the cones, as will be readily understood. Theouter casing H is of course connected with an outer pipe, (not shown,)the annular space between these two pipes being connected with asuitable exhaust-fan to maintain the desired suction within theexhaustspace H3. The cap-plate Ais formed adjacent the feed-opening witha feed-plate A7, and the adjacent part of the casing is formed with ahinged member H5, hinged to the casing at the point'H7 and pressed.inward toward the condenser-cone by the spring HS, so that this hingedmember, which is provided with a friction-roll H6 along its lower edge,presses against the bat of material formed on the condenser-cone I. Thebat'becomes disengaged from the cone at the lower portion of the samewhere the shield I5 cuts olf the suction, so that the bat iscontinuously fed down the feed-plate A7 and into the feedopening A3under the feed-cone. In this manner a bat of material of uniformthickness at all points is continuously supplied to each of thefeeding-openings A3, which extend from the axis ofthe press to thesizingcollar B7 at the top of the heling-chamber; also, since the apicesof the condensingcones substantially coincide with the axis of thebaling-chamber, the length of the bat ofV material supplied from thesecones to va- IOC lio

rious parts of the feeding-slot are proportionate to the distance fromthe center of the baling-chamber, and therefore the bat is correctlydistributed throughout all parts of the resulting bale.

As is well known in this art, the rotating cap-plate A, operating inconnection with the baling-chamber B, serves to produce within thebaling-chamber a continuous formingbale composed of superposed helicalribbons of material. This continuous bale is governed in its movementlongitudinally of the baling-chamber by the v ejector-wheels E, whoseconstruction and operation are substantially similar to those shown inmy Patent No. 671,918, April 9, 1901, As is best shown in Fig. 6, theejector-shafts E8 are mounted in suitable bearings Ewon the lower partof the baling-chamber, and the two IIS ISO

ejector-wheels E, formed with the bale-gripping spikes e, projectthrough suitable ejectorslots E2 into the baling-chamber. Splined to theouter end of each of these ejectorshafts is the skew-gear E, the teethE2 of which mesh with the skew-teeth E3 upon the crown-gear E4. Thiscrown-gear is mounted upon the lower end ol' the baling-chamber by asuitable collar E, is rotated at any desired speed relative to thebaling-chamber by the gear E5 upon its edge. In this way, as will beevident, each one of the ejector-wheels is rotated at the sameperipheral speed and engages the continuous bale within the chamber andpositively feeds it through the chamber at any desired rate. In this waythe density of the resulting` bale may be varied, as will be manifest.

The retainer-slots B2 extend longitudinally of the baling-chamberbetween the two ejector-wheels, mounted upon a tor-shaft. Each of theseretainer-slots is provided with the shoulder B3, so that the lower endof this slot is wider than the portion of the same above this point. Theretainer-slots, as is shown, extend to a point near the upper end of thebaling-chamber, as is shown in Fig-1, to the upper end of thecylindrical portion of the baling-chamber. The upper portion of theretainer-slots are open for the convenient insertion of the retainersinto the bale wi thin the chamber, and the bridge-pieces B4, extendingaround this part oit'` the retainer-slots, serve to strengthen the upperportion of the baling-chamber. The retainer-guides C3 are formedadjacent the retainer-slots and serve to maintain the retainers inproper position with respect to the bale. The upper retainer-guide C3 isformed with a cam portion C, and the lower retainer-guide at the otherside of the retainer-slot is formed with a cam portion C5. Thesecam-guides serve to force the retainer inward.

The retainer shown in perspective in Fig. 5 is formed with a bodyportion D, connecting the two feet D D2, having the sharpened points D3and D4, respectively. Upon the heels of the retainer-feet are formed thecam portions D5, D, and D7 upon the upper l'oot and the cam portions D8,D2, and D0 upon the lower foot D2, as is shown in that figure. The upperretainer-cam C, formed on the member C, projecting from the side of thebridge-piece B4, has, as is shown in Fig. 2, only a singlegripping-groove, which engages the retainer-cam D5 and holds it inproper position in the groove, the point D3 of the retainer having beeninserted in the retainerslot B2, and the foot D2 being positively guidedinto the bale by the edges of the slot and by the retainer-cam C', as isshown in Eig. 2.

The upper retainer-guide, formed on the bolted to the same, and4 bereadily seen single ejec-` member C2, is provided below the point C4 inEig. l with a second gripping-groove C3, which engages the cam DG uponthe upper retainer-foot D31, as shown in Fig. 3, a section at thispoint, and the retainer-guide at this point also comes in contact withthe cam D7 on the retainer-foot, so that the retainer is held inward atthis point throughout the whole rearward extent of the foot. It willthat since the retainers are placed in the oblique position indicated atF ig. 1, the upper foot of the retainer being at one side of theretainer-slot and the lower toot being at the other side of the slot toengage the lower retainer-guide, the upper retainercam must be cut awayabove the point C4, since otherwise the body of the retainer near theupper foot of the same would come in contact with the gripping-ledge andthe coaction of the retainer-cams with the cam-guides would not becorrect.

The lower retainer cam guides C5 are formed on the interior of therelieved portion B5 of the lower end of the chamber, as is shown in Eig.l, and, as is indicated in Fig. 4, this cam-guide is formed with twogrippinggrooves, which engage the cam portions o' the lower foot of theretainer throughout its whole rearward extent to positively force thisfoot into the continuous bale. Both the upper and lower retainer-guidesbelow the cam-guides are parallel to the axis of the press, so that theretainer once having been forced into the bale is held positively inthat position by the retainer-guides as it moves, together with thebale, through the balingchamber. The operation of these retainers inseparating and holding separate bales in proper position is as follows:The balingchamber being iilled with a. continuous bale, which is liedthrough the chamber at a definite rate by the ejectors, a set ofretainers are successively inserted through the spaces BG within thebridge-pieces B4, so that the upper feet of these retainers pass throughthe retainer-slots B2 and are forced to a slight extent into the bale byany suitable means, so that they retain their position longitudinally ofthe bale. are placed at the other side of the retainerslots in positionto properly engage the camguides (J5. Then the lower points of theretainers are also forced to some slight extent into the bale to travelwith the same. Then this set of retainers, which of course are forcedinto the bale symmetrically, as indicated in Fig. l, engage thecam-guides, which The lower feet of these retainers IZO force the upperand lower points of the retainers readily into the forming-bale, andwhen the retainers have been forced into the bale to the extent shown inFig. l thereafter they travel with the bale through the balingchamber.Vhen the upperieet of this'set of retainers comes into the open portionof the retainer-slots below the bridge-pieces B4,

ISO

another set of similar retainers are inserted' in like manner into theforming-bale, the

lower points of this second set of retainers being inserted into thebale directly alongside of the upper feet of the first set of retainers.This second set of retainers is engaged by the cam-guides, forced intothe bale, and fed forward with the bale in a simin lar manner. Thisoperation is repeated, and it will be seen that a series of separatebales are ejected from the baling-chamber and that each bale will beheldin proper compressed position by the set of retainers extending fromend to end ofthe same. These retainers on each bale may of course beheld temporarily in position as the bale issues from the lower end ofthe baling-chamber by straps or by any suitable means. As the separatedbales issue from the press they may be readily separated from thecontinuous bale within the baling-chamber by any desired means, and itwill'be notedin this con nection that the feet of the retainers enteringthe continuous bale serve to separate it into separate bales. Permanentbinding means are now applied to each bale ina well-known manner, or, ifdesired, the retainers may be rigidly secured in position and constitutethe permanent binding means.

Although I preferably form the chamber containing the retainer slots andguides integral with thel chamber which coacts with the cap-plate toform the bale and also form the ejectors or other bale-governing deviceson this chamber, it is not necessary that these members be formed as asingle piece. The retainer-guides should, however, be formed on aslotted bale-supporting chamber through which the bale is fed.

It will of course be understood that it is not necessary to form theretainers exactly as I have disclosed. The number of cams upon the feetof these retainers might be varied, and the shape of' these cams mightbe varied from what I have disclosed in the drawings. Readily-releasableretainers might be used in this form of' press. Furthermore, it is notnecessary in all cases that camguides be formed adjacent ytheretainer-slots to automatically force these retainers into the bale asthey travel with the bale through the baling-chamber. Other means offorcing these retainers into the bale might be employed. The exact shapeof the retainers and of the retainerslots and the number o1c theseretainers and retainer-slots might be varied, although the points of theretainers should project sui'liciently far into the forming-bale to holdthe bale in position and prevent rexpansion of the same after the baleissues from the press, and the feet of the retainers should be madesuHiciently long to accomplish thisresult.

Instead of the form of ejectors which I have just described any othermeans of regusuitable relieved portions may be lating the movement ofthe forming-bale through the baling-chamber may be employed, and inFigs. 7 and 8 I show a series of bale-governing elements F F, pivotallysecured to the lower end of the baling-chamber Bo by the heavy pivots FThe clamping-ring F 3, secured to the lower end of the baling-chamber bybolts, is provided with the clamping-screws F 4, which serve to adjustthe pivoted members F in any desired position, the lock-nuts 'shownholding the clamping-screws in place. As is indicated, the lower end ofthe baling-chamber is formed with a slight taper F2, so that themovement of the bale from the baling-chamber is resisted by this taperedportion. The baleegoverning elements F serve to increase the frictionalgrip of the lower end of the baling-chamber upon the bale, and infthisway a greater or less resistance is oered to the longitudinal movementof the bale. The speed of movement of the bale, and therefore thedensity of the bale, are regulated in this manner. As is shown in Fig.'7, the retainerguides C73 and C75 areformed between the bale-governingmembers, and the retainerfeet D71 Dm'shown in this figure are formedwith cam portions and operate in connection with the retainer-guides, ashas been already set forth.

In the modiiied-form of baling-press which I have disclosed in Figs. 11to 13 the balingchamber B10 is formed with the retainerslots B2, as hasalready been described, and also with the longitudinal slots B12, asindicated, These slots are formed at their lower portions with an inwardtaper, so that the continuous bale passes without interference past thelower end of these slots. It desired, formed in the lower part of thebalingechamb er as a continuation of these slots, so that in this mannerthe continuous bale engages the balingchamber throughout only a portionof its circumference. The heavy sleeves M pass about the bridge-piecesand serve to hold the baling-chamber together and to resist the internalpressure of the bale upon it. In this way the baling-chamber below thesizingcollar at its upper end, which as is shown in this ligure, isformed cylindrical and without any taper, may, if desired, be formed toengager the continuous bale only throughout the ribs B11, in which theretainer-slots and retainenguides are formed, as has already beendescribed. The retainers in this case operate in an exactly similarmanner to what has been `already disclosed', and the cap-plate and theparts carried thereby alsooperate in a similar way. I have shown in thiscase a different form of ejector, consisting of a series of screwejectors K', having a conical bodv and being formed with a multiplehelicalv ridge or screw-thread K of varying height throughout the bodyof the ejector. The

lO.l

IIC

axes of these screw ejectors are inclined slightly to the axisof thepress, so that the ejector-threads engage the forming bale through theejector-openings B14, inclined, as is indicated at B15, to a greater andgreater extent as the bale moves forward. This gradual impingement ofthe ejectorthreads upon the forming bale is very beneficial, since inthis manner less power is required to operate the ejectors. Each ofthese ej ectors is rigidly secured to an ej ector-shaft K2, mounted, asis indicated, in suitable bearings K5 at the lower end of thebalingchamber B10. Bigidly secured to these shafts are theejector-pinions K1, which mesh with and are driven by the teeth M4 ofthe large ejector-gear M, as is indicated. This gear is mounted in thebearing h in the lower end of the baling-chamber'and secured in positionby the sectional clamping-collar M2, bolted to the chamber. This gear isrotated about the baling-chamber at any desired rate by the teeth M,with which a suitable driving-pinion engages.

In Fig. 13 I have shown a modified form of screw ejector, formed with aconical body K10 and with a helical ridge K12, of graduallyincreasingheight throughout the ejector. This ejector is mounted, as indicated inthe bearings M15 M1, which engage the ejectorshaft K12. The ejector-pinion K13 is rigidly secured to this ej ector-shaft and mesheswith the teeth M14L of the large ejector-gear M10, driven by means ofthe teeth M13 on its edge. This gear is mounted in a suitable bearingM11 on the lower end of the baling-chamber B10 and is clamped inposition by the collar M12, bolted to the baling-chamber. It will ofcourse be understood that this screw ejector projects through a suitableopening into the baling-chamber and'engages in a manner similar to theejector K'the continuous bale within the chamber. The height of theejector-threads or helical ridges formed on these screw ejectors must besufficient so that the series of ejectors employed grips the formingbale within the chamber sufficiently to prevent any slip of the balepast them, and as the ejectors are rotated they serve to positively feedthe forming bale through the baling-chamber at any desired rate. Sinceall the screw ejectors of a set operate in unison, each one tends tofeed the bale forward at the same rate, as will be understood.

It will of course be understood by those familiar with this art thatnumerous modifications may be made in the baling-presses which I havedisclosed. Furthermore, it is possible to employ these bale-separatingretainers in connection with a press adapted to produce continuously abale of rectangular cross-section. The baling-chamber in this 4casewould of course be provided with suitable longitudinal retainer-slotsand retainergrooves. Suitable means would also be employed in this caseto regulate the movement of the continuous bale through the press.Numerous other modifications might be made, and parts of my baling-pressmay be employed apart from the others. I do not, therefore, wish to belimited to the disclosure which I have made in this case but what Idesire to secure by Letters Patent is set forth in the appended claims.
